The home of the "Happiest Place on Earth" has been breeding killer jihadists and Muslim zealots for years.

Omar Mateen, the cold-blooded mass murderer who gunned down 49 people at an Orlando gay nightclub and wounded 53 more before police took him out late Sunday, may have worked alone. But he operated in the larger context of a teeming, terror-coddling paradise.

While tourists from around the world soak up sunshine and dreams at Disney World, Islamic extremism festers around them.

Schools:The Muslim Students Association, founded by the radical Egyptian Muslim Brotherhood whose stated purpose is to wage "grand jihad" on America, is active at the publicly funded University of Central Florida in Orlando. The group defiantly brought un-indicted terror co-conspirator Siraj Wahhaj (right) to campus. He's the black Muslim convert and inflammatory imam tied by federal prosecutors to the 1993 World Trade Center bombing and New York City landmarks bombing plots.

Wahhaj served as a character witness for convicted terror mastermind Omar Abdel Rahman (the Blind Sheik), called for replacement of America's "constitutional government with a caliphate" and roots for our nation to "crumble" so Muslims can take over. UCF funded a Muslims "da'wa" (conversion) seminar and with an endowment by the Saudi-supported International Institute of Islamic Thought sought to create an Islamic Studies chair to "help the Ummah regain its intellectual and cultural identity and re-affirm its presence as a dynamic civilization."

The IIIT, also a Muslim Brotherhood affiliate, donated at least $50,000 to a "think tank" run by Sami al-Arian that served as a front group for the Palestinian Islamic Jihad. While al-Arian, a Muslim Brotherhood member dating back to the 1980s, served as a computer science professor at Tampa's University of South Florida, he toured the country raising money for terrorism overseas. Investigative reporters and the feds caught al-Arian on tape inciting his attendees against, America, Israel "and their allies until death." The left-wing academic pleaded guilty to a terror-fundraising conspiracy charge in 2006.

Al-Arian brought Palestinian-born Ramadan Shalah to teach at USF and head his "think tank" for a spell. Shalah left the school in 1995 and resurfaced as head of Syria's Islamic Jihad. He remains one of the FBI's most wanted indicted terrorist fugitives.

Mosques: Mateen's homicidal hatred for gays didn't exist in a vacuum. Mateen's neighborhood mosque in nearby Fort Pierce, Florida, was also the house of worship of Moner Abu-Salha, an American jihad recruiter and suicide bomber who blew himself up in Syria last year. The Palm Beach Postreported this week that Abu-Salha had posted videos of an imam's death-to-gays rant on Facebook.

In South Florida, the Darul Uloom Institute mosque in Pembroke Pines counted al-Qaida jihad pilot Adnan el-Shukrijumah (allegedly killed in a raid in Waziristan by the Pakistan military in 2014) and convicted jihadist Imran Mandhai—who plotted with fellow mosque attendees Hakki Aksoy and Shueyb Jokhan to blow up power stations, synagogues and a National Guard armory—among its worshipers.

Shukrijumah's brother still lives in Broward County near the Darul Uloom mosque and has posted social media videos condemning "moderate" Muslims, blaming 9/11 on Jews and promoting the caliphate. Darul Uloom's imam is a gay-bashing, Christian-bashing, Jew-bashing bigot who has publicly stated that at least one of the 9/11 hijackers prayed at his mosque.

Jails: Florida's prisons and penitentiaries are unfettered cesspools for jihad radicalization and recruitment. Convicted al-Qaida dirty bomb plotter Jose Padilla (a.k.a. Abdullah al Mujahir) was introduced to Islam while serving time for an armed road rage incident in Sunrise, Florida. The above-named Abu Taubah radicalized nearly 40 fellow inmates while behind bars on a weapons conviction. He was freed last summer by U.S. District Judge Gregory Presnell after time served despite prosecutors' pleas to add 10 years to his sentence based on enhanced terror charges.
